RVE and homogenization technique

RVE and homogenization technique

RVE and homogenization technique

(OP)
Hello everybody,

For the purpose of describing macroscopic thermo-mechanical behavior of BEOL (Back End Of the Line) interconnect structure, the heterogeneous BEOL stack (Cu, porous materials...) may be approximated as a homogeneous medium with certain effective moduli and Poisson ratios. I'm trying to implement such methodology (homogenization) with ANSYS for 2-D or 3-D models but without success. I can't find the right boundary conditions...

Can you help me ?
Do you have some examples/tutorials ?

Thanks in advance.
